Last week, on April 2, 2012, the 1940 United States census was released to the public in digital format by the National Archives in conjunction with the U.S Census Bureau at http://1940census.archives.gov

Veiled in secrecy for 72 years because of privacy protections, the 1940 U.S. census is the first historical federal decennial survey to be made available on the Internet initially rather than on microfilm.

In a great example of a private/public partnership, Archives.com’s parent company partnered with the National Archives to provide the public with free digital access to the 1940 Federal Population Census.

Miriam Kleiman, spokeswoman for the U.S. National Archives, told The Associated Press that the Archives’ 1940 census site registered more than 22 million hits in just four hours from almost 2 million users on its very first day of release. It is extremely popular already with librarians, researchers and genealogists researching their family tree.

Data from the Great Depression

Archivist Connie Potter, in an entertaining video about the Archives’ digitization project, explains that the reason this census is so amazing is because it describes “the country during the Great Depression. It reflects all of the economic dislocation, how many people were immigrants, how many people had what level of education.”

Last week’s release of digitized information covers detailed records on 132 million people living in the United States at the end of the Depression and a year before Pearl Harbor.

The census data was transferred to microfilm during World War II, and in 2009, National Archives personnel began digitizing those records, culminating in the release of the database last week.

Over 3.9 million images were digitized, providing a bonanza for researchers.

Some interesting facts about the 1940 Census

The Census Bureau began the 1940 census with extensive long-term planning, recruiting and training. Back in 1940, about 120,000 census-takers, called enumerators, spread out across the U.S. and territories, going door-to-door to interview families.

Enumerators both then and now can face challenging situations when gathering the data to tabulate the census, from trudging through fields or mushing a dog sled across the snow.

It’s interesting to note the questions that were asked on the 1940 census form. One of the fifty questions the enumerators asked Americans in 1940 reflected the more formal societal structures of the time: “What was the Relationship of this person to the head of the household, as wife, daughter, father, mother-in-law, grandson, lodger, lodger’s wife, servant, hired hand, etc.?”

Another question was very relevant for a Depression-era nation where children as young as 14 still worked, and millions of out-of-work Americans were given “public emergency” jobs around the country under Franklin Roosevelt’s New Deal programs. One was the Works Project Administration(originally the Works Progress Administration) or WPA, which was the “largest and most ambitious New Deal agency and employed millions of unskilled workers to carry out public works projects,including the construction of public buildings, roads and dams, as well as operating large arts, drama, media, and literacy projects.”

Another New Deal program mentioned in the census was the Civilian Conservation Corps or CCC. It was designed to provide employment mostly for young men in relief families who had difficulty finding jobs during the Great Depression (there were separate programs for veterans and Native Americans), while at the same time implementing a general natural resource conservation program in every state and territory for the “conservation and development of natural resources in rural lands” owned by federal, state and local governments. Many trees were planted and national and state parks built and preserved by the CCC.

Another youth-focused program referenced was the National Youth Administration or NYA that focused on providing work and education for young Americans between the ages of 16 and 25.

Thus, it makes sense that this 1940 census question asked “Persons 14 Years Old and Over” to classify their employment status during the time of the census-taking (March 24-30, 1940) as follows:

Was this person AT WORK for pay or profit in private or non-emergency Government work during week of March 24-30? (Yes or No).

If not, was he at work on, or assigned to, public EMERGENCY WORK (WPA, NYA, CCC, etc.) during week of March 24-30? (Yes or No).

How to Use the 1940 Census

Even for those not steeped in genealogy research will find it thrilling, like I do, to see the excitement build over the release of these images. It might be fun to look up my ancestors because I know my grandfather worked for the W.P.A. I’m also interested in looking at the various trends and metrics available on housing to see if there is any correlation to the current economic situations.

Visit the National Archives pages to see the various resource location aids, enumerator training videos, and question templates that have been gathered for your use. Based on the times, there were specific instructions for enumerators to get a count of temporary housing such as huts, tents, and cabins as of a point in time. Here’s one bit of instruction to help clarify how to count the large transient population: “Persons in hotels, tourist or trailer camps, missions, and cheap one night lodging houses (flophouses) will all be enumerated as of the evening of April 8th”.

Help Tag the Images

The Census Bureau is appealing to the public for help indexing and meta tagging the images. This is a genealogy crowdsourcing project to ensure the 3.8 million images are indexed and freely searchable online. You, too, can register to be a 1940 Census Blog Ambassador and get a nifty badge for your page!
